Title: Improvements in and relating to a method and machine for producing solid moulded bodies, especially ice cream bricks
IPC: A23G9/10
Filed: 1954-04-30
Abstract: 744,583. Ice-making. HOYER, O. G. April 30, 1954 [May 11, 1953], No. 12644/54. Class 29. Relates to apparatus for making solidified moulded bodies e.g. of ice-cream wherein a mould 1 is rotated step-wise in a horizontal circular path and carries rows of cells 2 depending into a bath 15 of refrigerant and into a thawing zone, the cells being filled with liquid at one point, having sticks inserted after partial solidification and, at the completion of thawing, being aligned with grippers which descend to grip the sticks and are raised to remove the bodies which may then be dipped in chocolate and released. According to the invention, the refrigerant bath is stationary and has end openings through which the cells enter and leave the bath without changing their level. Refrigerant, e.g. calcium chloride brine, is supplied by a pipe 10 to a distribution duct 13 from which it flows through apertures 14 in plate 12 into bath 15 to cool the cells 2. It overflows the bath into a heat insulated trough 17 from which it is returned to the refrigerating apparatus by a pipe 18. The cells enter and leave the bath through openings defined by sluices 22, 21 which closely conform to the shape of the moulds and which are long enough to take two radial rows of cells 2 to reduce the loss of refrigerant at the ends of the bath. They may be removeable so that they may be replaced to suit different shapes of cell. Any refrigerant passing through the sluiceways drips from the cells and falls into trough 17. Extra openings in plate 12 may be provided at the ends of the bath to compensate for such refrigerant loss. At the thawing zone, a container 27, fitted with thermostatically controlled electric heaters 29 supplies liquid through a pipe to a pump 26 which supplies it through a hose 28 to a pipe 31 feeding into a container 25. Container 25 and pipe 31 are carried by a vertical rod 32 guided between rollers 33 carried by a plate 34. This plate is reciprocated horizontally by a hydraulic cylinder (not shown) and the container 25 is raised and lowered by a hydraulic cylinder 39. In operation when the mould moves one step, the thawing container moves with it and then, when the mould is stationary, descends, moves back one step and rises again. The container surrounds three rows of cells and thus each cell is immersed in the thawing liquid three times. The mould is provided with perforations 43, one for each radial row of cells and, when the thawing container is raised, rod 32 engages one of the holes so as to advance the mould one step when the thawing container is moved, by its hydraulic cylinder. Adjustable stops (not shown) limit the horizontal movement of the thawing container. Interchangeable moulds 1, having different cell arrangements, are provided, the cells being so disposed that a radial row is present beneath each of the filler, the stickinserting apparatus and the grippers at the same time.

[Class 60] [Also in Group XXII] The teeth of a toothed blade employed for cutting lengths from printed web are formed in the blade by means of a grinding-wheel or rotary file which operates successively on both faces of the blade to form teeth bevelled on both faces. The grinding-wheel 1, shaped according to the form of the teeth required, is journalled at one end of a lever 4 pivoted at 5 in brackets 6 of a slide 6', and is driven by a belt 11 from an electric motor 10 on the lever. The blade 8 is held on a part 12 by a clamping plate 15 and bolts 16, the part 12 having end shafts 13 journalled in brackets 14 on the machine frame 7, and one shaft 13 has thereon an arm 13<1> movable between adjustable stops 17, 18 so that the blade may lie in either of two angular positions for both faces to be operated upon by the wheel 1. The lever 4 is moved about its pivot to bring the wheel 1 into and out of working position by a cam 21 carried by a shaft 23 and engaging a follower 20 on an arm pivoted to the arm 4 and adjustable by a screw 22. to adjust the depth of cut of the wheel. The work-holder is rocked, at times when the wheel 1 is raised, by a rod 26 pivoted at 25 to the arm 13' and formed as a sleeve to receive a plunger 27 on a rod 28, springs 34, 35 lying one on each side of the plunger so that the rod 28, which is connected to a crank pin 29 adjustable in a slot 30<2> in a disc 30 mounted on a main shaft 31, may move after the work-holder has contacted with one of the stops 17, 18. In order to move the holder 12 and the blade 8 from one tooth position to the next, the slide 6', which is movable on ways 6<2> on the frame 7, when the wheel is raised from the work, has thereon a nut in engagement with a lead screw 36, partially rotated by means of a ratchet wheel 37 thereon, with which engages a pawl on a lever 39. The lever is oscillatable about the axis of the screw 36 by means of a cam 42 on the shaft 31 through a lever 41 and a link 40, and the shaft 23 is driven by gearing 32 from the shaft 31 so that the wheel 1 makes two movements towards and from the work for each forward movement of the work-holder; both faces of a tooth are thus ground. The cam 21 is caused to move with the slide 6' by cheeks 46 thereon, which engage a carrier slidable but not rotatable on the shaft 23 and having the cam 21 mounted thereon; the shaft 31 is driven, through gearing 31', from a motor 31<2>.
